Abstract

A system and method for optimizing defragmentation of content in a content delivery network (CDN). In an example, a manifest available to the content delivery node with respect to a particular content as well as segment files stored in a database cache of the content delivery node are analyzed to determine if any segment files referenced by the manifest are absent from the database cache. If so, one or more delivery rules associated with the content delivery node based on historical ABR asset delivery patterns may be applied to determine representations of the absent segment files that satisfy the one or more delivery rules. After determining compliant representations of the absent segment files, they may be pulled from another content delivery node of the CDN (e.g., a parent node or an edge server node).

Abstract

An HF combiner includes a housing having a common terminal and n signal line terminals. The n signal line terminals are coupled to the common terminal within the housing via one of n filter paths in each case. A circuit board arrangement is used for outcoupling and separately transmitting low-frequency signals, and includes a common terminal contact and n signal line terminal contacts. Each of the n signal line terminal contacts is electrically connected or connectable to the common terminal contact via one of n bypass lines in each case. For this purpose, a control device controls n signal line switching devices. When an AISG signal is detected at one of the n signal line terminal contacts, the control device is designed to electrically connect the particular one of the n signal line terminal contacts, at which the AISG signal has been detected, to the common terminal contact.

Abstract

A method implemented to provide a virtual network to tenants requiring bandwidth in a cloud computing environment is disclosed. The method starts with receiving a request for a task at a network device, the request including a first parameter indicating VMs required, a second parameter indicating bandwidths the required VMs need, a third parameter indicating a duration of the task, and a fourth parameter indicating a deadline of the task. The network device then selects a starting time and a bandwidth allocation of the task, where the bandwidth allocation is shrank to be smaller than the second parameter indicating, and where the selection aims at minimizing a measurement of cloud resource utilization considering consumptions of both VMs and bandwidth. Then the network device allocates VMs for the request at the starting time with the bandwidth allocated at a particular location in the cloud computing environment.

Abstract

A method implemented to provide a virtual network to tenants requiring bandwidth in a cloud computing environment is disclosed. The method starts with receiving a request for a task at a network device, the request including a first parameter indicating VMs required, a second parameter indicating bandwidths the required VMs need, a third parameter indicating a duration of the task, and a fourth parameter indicating a deadline of the task. The network device then selects a starting time and a bandwidth allocation of the task, where the bandwidth allocation is shrank to be smaller than the second parameter indicating, and where the selection aims at minimizing a measurement of cloud resource utilization considering consumptions of both VMs and bandwidth. Then the network device allocates VMs for the request at the starting time with the bandwidth allocated at a particular location in the cloud computing environment.

Abstract

Media content is delivered to a variety of mobile devices in a protected manner based on client-server architecture with a symmetric (private-key) encryption scheme. A media preparation server (MPS) encrypts media content and publishes and stores it on a content delivery server (CDS), such as a server in a content distribution network (CDN). Client devices can freely obtain the media content from the CDS and can also freely distribute the media content further. They cannot, however, play the content without first obtaining a decryption key and license. Access to decryption keys is via a centralized rights manager, providing a desired level of DRM control.

Abstract

A system and method for effectuating channel changes in a multicast adaptive bitrate (MABR) streaming network using a dedicated bandwidth pipe for burst transmitting a requested channel's data. A video management agent is configured to stitch burst-transmitted data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. Once the data from the regular channel stream is properly joined, burst transmission ceases and the bandwidth consumed for sending burst-transmitted data is released.

When a streaming network back office receives a request from the streaming client device for delivery of a particular content, wherein the request includes external device information of one or more external A/V devices connected to the streaming client device, a bandwidth is determined for streaming the particular content to the streaming client device and a request may be made to a content delivery network to create a distribution pipe having the bandwidth to accommodate the delivery of the particular content. A manifest file is provided to the streaming client device that includes one or more pointers that point to content segments of the particular content.

Abstract

A system and method for effectuating channel changes in a multicast adaptive bitrate (MABR) streaming network using temporarily borrowed bandwidth from a shared progressive download ABR bandwidth pipe for downloading a requested channel's data in a recovery segment by issuing an HTTP request. A video management agent is configured to stitch the recovery segment's data with the regular channel stream during the channel change to generate a hybrid stream, which is multicast streamed toward the requesting device. Once the data from the regular channel stream is properly joined, recovery segment downloading ceases and the bandwidth consumed for sending recovery data is released back to the progressive download ABR pipe.

Abstract

A system and method that utilize a learning system to maintain a set of geographical locations indicating an area where network data coverage is poor. When it is determined that a client device is moving towards such an area, the client is forced or instructed to switch to a lower delivery bitrate for video segments in order to force the client's Adaptive Bit Rate (ABR) playback buffer to fill itself with enough low-quality video segments to enable the client to cross the area without video playback interruption. Thus, the client mobile device may be preemptively forced to choose the lowest bitrate specified in a manifest file for the delivered video segments as the bitrate for downloading video segments when approaching the poor coverage area. Hence, the client device can maintain a minimum level of Quality of Service (QoS) when moving through network areas with poor data coverage.

Abstract

In one embodiment of a network pipe optimization method, a network element may obtain at least one of a push pipe utilization report and a pull pipe utilization report from each distribution node of the content delivery network. Based on the utilization reports, the network element may determine new push pipe weights and new pull pipe weights for distribution pipes associated with each distribution node of the content delivery network. Using at least one of the new push pipe weights and new pull pipe weights, a network pipe utilization model associated with the content delivery network may be simulated. Responsive to determining that the simulated network pipe utilization model yields an improved utilization of the content delivery network, the new push pipe weights and new pull pipe weights may be distributed to each distribution node in the content delivery network.

Abstract

A multiplex filter has at least n filter chambers which are surrounded by a housing and/or at least one insert positioned in the housing. A metal dividing device is constructed in each of the n filter chambers, dividing each filter chamber into m resonator chambers, wherein m≥2. The resonator chambers are coupled perpendicular to the H fields and/or parallel to the central axis or with a component essentially perpendicular to the H fields and/or parallel to the central axis. A common connection is guided into the first filter chamber via a first opening in the housing, and is coupled in the same to the m resonators of the m resonator chambers. As a result of the fact that the coupling is established perpendicular to the H field, the resonator can have a very compact construction.

Abstract

A system and method for providing guaranteed channels in a switched digital video network using multicast adaptive bitrate (ABR) streaming. In one implementation, when a request for a guaranteed channel is received from a subscriber station (e.g., a set-top box or STB), a determination may be made as to which edge QAM device the requested channel is assigned to. A bandwidth pipe modeling may be performed for the assigned edge QAM to determine an optimal bitrate of a particular MABR stream that may be packed into the edge QAM's bandwidth pipe. Thereafter, the particular MABR stream may be joined to facilitate streaming of the requested channel via the QAM serving the subscriber station.

Abstract

A system and method for providing VOD/NPVR content in a switched digital video network using unicast adaptive bitrate (ABR) streaming. In one implementation, upon receiving a notification from a back office pursuant to the VOD session request from a subscriber station (e.g., a set-top box or STB), a bandwidth pipe modeling process is operative to model a bandwidth pipe corresponding to each edge QAM device configured to support VOD sessions for selecting a particular edge QAM device that can best accommodate the requested VOD session. Bitrates of UABR streams of existing VOD sessions of the selected edge QAM device may be adjusted in order to accommodate a particular UABR stream at a chosen bitrate for the requested VOD session. UABR allocations of the selected edge QAM's bandwidth pipe may be effectuated for the existing VOD sessions and the requested VOD session as needed. A response message including one or more session frequencies, if the session request is accommodated, may be transmitted to the requesting subscriber station.

Abstract

A source edge router initiates point-to-point (P2P) label switched paths (LSPs) to multiple receiver edge routers, sends one or more PATH messages to one or more nodes downstream of the source edge router for the P2P LSPs, wherein each one of the set of PATH messages includes a same identifier of a point-to-multipoint (P2MP) LSP that includes a session object that contains a tunnel identifier and a P2MP identifier, and receives from each of those nodes downstream of the source edge router, a set of one or more RESV messages, wherein each one of the received RESV messages received from a respective node downstream of the source edge router includes the identifier of the P2MP LSP and a label allocated by that node downstream of the source edge router.

Abstract

A differential phase shifter assembly with n striplines positioned concentrically with one another, on the opposite stripline ends of which connecting points for connecting lines leading to radiators are provided, where n is a natural integer greater than or equal to 2. A feeding and/or tapping device is pivotable about a central and/or pivot axis, and is therefore pivotable over the plurality of striplines while establishing a primary capacitive coupling. A central feed serves to feed the feeding and/or tapping device. At least one to n−1 secondary capacitive couplings are additionally provided. The one or more secondary capacitive couplings are provided on the side of the feeding and/or tapping assembly facing the primary capacitive coupling. For the at least one additional secondary capacitive coupling, at least one additional branched feeding and/or tapping device is provided, which together with the feeding and/or tapping device is pivotable about the central and/or pivot axis.

Abstract

A scheme for optimizing segment sizes for an adaptive bitrate (ABR) streaming client engaged in a current ABR streaming session. In one implementation, a determination is made whether a wireless UE device executing the ABR streaming client is approaching a radio white spot area. If so, a video buffer of the ABR client is configured to preload a fixed number of segments having an adjusted size depending on the duration of the radio white spot area. The preloaded segments may comprise lower quality video segments, and as the wireless UE device exits the radio white spot area, the segment size and/or bitrates may be restored depending on the signal quality.

Abstract

A scheme for managing bandwidth in a multi-client environment including one or more ABR clients and, optionally, one or more non-ABR clients. When an ABR client enters a sleep phase of its duty cycle, phantom tokens may be issued to simulate full capacity of the network link, wherein phantom packets are used for ABR bandwidth calculation. Any extra bandwidth that would have been used by another ABR client to artificially inflate its video quality may be optionally allocated to a non-ABR client engaged in a progressive download session in the same bandwidth pipe.
